Successful treatment of severe psoriasis and psoriatic arthritis with adalimumab.

Adalimumab, a fully human-derived recombinant monoclonal antibody against tumour necrosis factor-alpha, has been shown to be effective for the treatment of patients with moderately to severely active rheumatoid arthritis. We report two patients with long-standing recalcitrant psoriasis and psoriatic arthritis who, after multiple treatment failures with conventional and experimental antipsoriatic medications, both responded to treatment with adalimumab. Significant clinical improvement was noted in both skin and joint disease in the two patients after several weeks of treatment with adalimumab. We are unaware of previous published reports of adalimumab therapy in patients with psoriasis and psoriatic arthritis.
